Notes
New PB on a tread mill, no wind resistance, no elevation previous best on the mill was 9.47 but also the disadvantage of losing time waiting for the belt to catch up with me. Did a section at start of 35 seconds at 10mph covering 156m, which would be 44.87 for 200m if no tailing off, this is similar to a predicted time of 43 seconds based on my time for 1km today (via calcs with degradation taken into account) and my own prediction of 46 seconds based on 17s for 80.5m.
